AMD中叫RVI
VT-d直接虚拟化:很多时候我们的真实机8196的网卡被虚拟成e1000的网卡,如果有VT-d,那么虚拟化可以直接让虚拟机调用真实
SR-IOV:多个虚拟化设备可以同时调用一个真实的硬件设备
KVM:Qumranet(now part of Redhat),是从Ovirt开发形成的。
Thick vs thin virtualization host:Thick,没有被定制过的虚拟化;thin,被定制过的虚拟化
nx:防止缓冲区溢出的指令集
ksm:相同内存页整合,当通过模板创建的虚拟机,调用同样的内存。(/sys/kernel/mm/ksm/pages_shared)
VirtIO:在全虚拟化中添加半虚拟化驱动。

Configure an NFS share on this server to be used as an ISO Domain? (Yes, No) [Yes]: ISO域配置,这里使用rhevm本机作为ISO域
Local ISO domain path [/var/lib/exports/iso]: /exports/rhevisos
Local ISO domain ACL - note that the default will restrict access to rhevm.pod0.example.com only, for security reasons [rhevm.pod0.example.com(rw)]:
Local ISO domain name [ISO_DOMAIN]: iso0
--== MISS CONFIGURATION ==--
Reports power users password: 报表的密码
Confirm engine admin password: 重复上面密码
[WARNING] Password is weak: it is based on a dictionary word
Use weak password? (Yes, No) [No]: yes 提示密码为弱口令
Would you like transactions from the Red Hat Access Plugin sent from the RHEV Manager to be brokered through a proxy server?(Yes,No) [No]:
The domain example.com has been added to the engine as an authentication source but no users from that domain have been granted permissions within the oVirt Manager.
Users from this domain can be granted permissions by editing the domain using action edit and specifying --add-permissions or from the Web administration interface logging in as admin@internal user.
oVirt Engine restart is required in order for the changes to take place (service ovirt-engine restart).
